Chipset Selection for the Best Motherboard
The chipset or core logic refers to the two main chips on the motherboard: Northbridge and the Southbridge.


Northbridge-The chip that is responsible for communications between AGP/PCIe bus, CPU, memory, and the Southbridge chip.

Southbridge-The Southbridge chip provides connections for the I/O (input/output) devices such as PCIe, USB, PATA, SATA, and the PCI bus. Note that the PCIe bus and the PCI bus are not the same
Memory Support for the Best Motherboard

Intel

The memory controller on Intel compatible motherboards is located in the chipset. Memory type, capacity, memory speed, and whether single or dual channel is determined by the chipset. Be sure to look at the motherboard’s memory specifications to determine compatibility and capacity before buying.

AMD

Most of the AMD K8 (Athlon 64 and Sempron) processors now have the memory controller integrated into the CPU. Here’s some additional information.


Socket 754 CPUs support single channel memory up to DDR 400.
Socket 939 CPUs support dual channel up to DDR 400.
Socket AM2 support up to dual channel DDR2 667.
Exceptions are the Athlon 64 X2 and the Athlon FX CPUs supporting dual channel memory up to DDR2 800.
